Time-Domain Bound States in the Continuum

We present the concept of time-domain bound states in continuum. We show that a rapid judiciously-designed temporal modulation of the refractive index in a spatially homogenous medium gives rise to a bound state in time embedded in a continuum of ...

New method for extracting quasi-bound states from the continuum

, 2008
22 pages, 10 figuresA new parameter-free method is proposed for treatment of single-particle resonances in the real-energy continuum shell model. This method yields quasi-bound states embedded in the continuum which provide a natural generalization of ...

Evolution of Degenerate Pairs of Bound States in the Continuum With Broken Symmetry

IEEE Photonics Journal
Bound states in the continuum (BICs) with exceptionally high quality factors ($Q$ factors) have become focal points in photonic device research, finding applications in nonlinear enhancement, laser generation, sensing, and beyond.

Anisotropy-induced band transition and merging of bound states in the continuum in gratings

Results in Physics
We propose the grating systems composed of anisotropic material and study the tunability of such anisotropy to the evolutions of bound states in the continuum (BICs) and leaky mode, as well as the band flip between odd- and even-mode.

Nonlinear nanophotonics and bound states in the continuum

, 2018
We reveal that nonlinear effects at the nanoscale can be enhanced by bound states in the continuum. We demonstrate SHG from subwavelength AlGaAs nanoantennas with record-high conversion efficiency when resonator parameters match the proper ...

The bound states of Fe impurity in wurtzite GaN

, 2012
A study on the bound states of Fe impurities in GaN by ultraviolet photoluminescence (PL) emissions is presented. Two elusive PL lines were observed at 3.463 eV (L1) and 3.447 eV (L2), respectively.

Asymmetric metasurfaces with high-$Q$ resonances governed by bound states in the continuum

, 2018
We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic) meta-atoms with broken in-plane symmetry can support sharp high-$Q$ resonances that originate from the physics of bound states in the continuum.

Experimental Observation of Time-Domain Bound States in the Continuum

Bound states in the continuum (BICs) traditionally describe spatially-localized modes embedded a within radiative continuum. Here we report the first experimental realization of time-domain BICs and anti-BICs, highlighting a new frontier for BIC physics.
